BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water leakage prevention device for a bridge such as a road bridge or a railway bridge or a road, and further relates to a water leakage prevention and display device provided with a night illumination device.

[0002]

2. Description of the Related Art Generally, a bridge such as a road bridge or a railway bridge has a floorboard, a main girder disposed on the bottom surface of the floorboard, a ground cover portion disposed on both sides of the floorboard, and a pavement laid on the top surface of the floorboard. It is configured to have. The main girder is mainly made of iron or concrete, and the floor plate is made of reinforced concrete. In addition, since a plurality of floor boards are connected to each other and the main girder floor boards expand and contract due to thermal expansion between the main girder floor boards, there are various types of girder floor boards that face each other at certain points from the bridge structure design at the time of girder erection. Required play space (distance between floorboards)
To have. In particular, in a bridge having two lanes, an up lane and a down lane, a median strip is formed in the central part (between the up lane and the down lane) and is formed along the longitudinal direction of the median strip. Vertical joints of the median strip are formed in the play space.

In such a bridge, rainwater, muddy water, etc. leak from the median strips and vertical joints to accelerate the aging of the concrete structure of the floor board and the iron members or concrete members of the main girder. Therefore, in the past,
A rain gutter was installed in the longitudinal direction at a location where even one point of rainwater cannot leak.

The above applies not only to bridges but also to general roads, and rain gutters have been installed in the vertical joints formed between the up lane and the down lane.

[0005]

However, the rain gutter cannot completely cover the longitudinal joints of the median strip and the longitudinal joints of the general road, and rainwater and muddy water are not covered by the rainwater between the rainwater and the floorboard. It flowed from the side to the bottom and flowed into the main girder, and water leakage from the vertical joints could not be prevented, and the aging of the floorboard and main girder could not be prevented. Further, since the clearance between the vertical joints of the median strip is formed at about 20 to 50 cm, there is a risk that the floor plates may come into contact with each other to cause cracks or damage to the concrete due to the occurrence of an earthquake or large vibration. .

In addition, since the ground cover and the median strip are hard to see when driving at night, there is a possibility that the car may hit the ground cover and the median strip only by lighting the vehicle, especially in a sharp curve. Specifically, a dedicated display device was installed in a dangerous place. However, in order to install the display device, it must be installed separately from the water leakage prevention device, which not only makes the device bulky but also increases the facility cost.

The present invention solves the above-mentioned problems, and prevents leakage of water from joints due to rainwater or muddy water to prevent aging of main girders and floorboards, and a buffer member is arranged between the floorboards. By doing so, it is an object of the present invention to provide an extremely efficient water leakage prevention and display device for bridges or roads that can take measures against vibrations such as earthquakes and can also display nighttime lighting.

[0008]

In order to solve the above-mentioned problems, a water leakage prevention / display device for a bridge or a road according to the present invention is constructed as follows.
That is, a water leakage prevention and display device for a bridge or a road, which is erected upward from a vertical joint formed on the bridge or the road, and is formed in a protruding shape upward so as to cover the vertical joint. Elastic body having a main body portion, a flange portion arranged so as to be connected to both sides of the main body portion, and a stand plate portion standing from the central portion of the main body portion toward the vertical joint portion. A water leakage prevention member formed of a member is provided, and a night illumination member is disposed on the water leakage prevention member.

Further preferably, the night lighting member may be a lighting member having an illuminant arranged on the upper portion of the main body portion and arranged continuously.

More preferably, the night lighting member is
It may be a reflection plate attached to the side surface of the main body.
